Siemens 6FX1118-4AB01 Industrial Control Module

Siemens 6FX1118-4AB01 is a SINUMERIK 3 digital input/output combination module that adds substantial I/O capacity to SINUMERIK CNC systems, delivering 48 digital inputs and 24 digital outputs all rated for 24V DC operation. Each channel supports up to 0.1 A, enabling reliable interfacing with sensors, safety interlocks, and actuators while maintaining compact wiring and direct board-level integration. This module is designed for SINUMERIK 3 control hardware and requires Basic Version 2 or later, with a caution that it is not compatible with Basic Versions 0 or 1. In typical machine-automation scenarios, the 6FX1118-4AB01 expands the CNC’s digital signaling for machine state, limit and proximity sensors, and control of auxiliary devices, helping engineers tailor the I/O topology to precise application needs while simplifying diagnostics and wiring within the control cabinet.
